SPINNING AND TWISTING IEZAPER AND OTHER EZB QUS MATERIALS.

1'0 166 whom it may concern Be it known that I, THOMAS ALEXANDER BOYD, asubject of His Majesty King George, King of Great Britain and Ireland,and residing at Glasgow, Scotland, have invented certain new and useful.Improvements in Spinning and Twisting Paper and other FibrousMaterials, ofwhich the following is a specification.

My invention relates to machines for spinning and twisting paper orotherfibrous materials into yarn or twine and has forits object meansfor damping the said mateduring the process of'spinnin'g or twisting andalso improved means of stopping and starting the spindles of such framesin conjunction with the said damping process.

My invention consists of a delivery roller,

adamping roller and a trough of water or other liquid so arranged thaton the-de-' the dampinglivery roller; being, stopped roller is liftedfrom contact with theliquid and thus ceases to damp the paper or othermaterial being spun or twisted.

Accompanying this specification is one sheet of drawings.

My invention also includes means of stopping the spindles in conjunctionwith the said delivery and damping rollers.

-In carrying out my invention in one arrangement in' which a strip ofpaper is drawn .from a roll, damped, twisted and wound on to a bobbin, Iemploy a' vertical ring twisting spindle 1, mounted on a spindle rail 2,a tin drum?) and a cord 4;, to drive the spindle 1, all ofordinary-construction. Onthe spindle I mount a bobbin 5', upon 6 isWound by means travelers 7 operated in the of a ring and On the framingIplace a top usual manner.

rail 8 above and behind-the spindle 1. On

the top; rail 8 1' mount a low delivery roller 9 driven-in relation tothe spindle 1 in the usual manner. Above the low de- I-mount a topdelivery roller 10, which-'s driven by frictional contactwith theformer. The top delivery i'bller10 has a groove 10 in which I place aring of india rubber or some soft substance adapted to grip and deliverthe paper strip 6 as it is being twisted.

The top delivery roller 10 is carried on a stud 11 fixed to the upperend of a bell Specification-of Letters Patent. Application filed April30,1914. Serial No. 835,515.

around the tin roller 3, and back to the spindle 1. When the PatentedMay 11, rate.

crank lever 12 which is mounted upon a shaft '13 in front of andparallel with the low delivery roller 9. The bell crank lever referredto has a horizontal limb 12 passing inward below the low delivery roller9. At the inner end 12. of the said bell crank lever 12 I suspend aweight 12 which'causes the top delivery roller 1i to press upon and getdriven by the low delivery roller 9. The horizontal limb 12 of the bellcrank lever "12 is lifted at its inner end 12 as hereafter described,when the top roller 10 has to be stopped. On the spindle rail 2 behindthe spindle 1 I mount a tension bracket 14 with a horizontal pivot 14 onwhich I mount a cord' tensionlever 15 extending inward toward the tin"roller 3,. and having at its inner end a tension roll 16. Thespi'ndlecord a is passed around the spindle wherve 1 over the tension roll 16,beneath and tension roll 16 is held at its highest point the-spindlecord 4 1 is tightened and drives the spindle 1. When it is lowered thespindle. cord 4 is slackened and ceases to drive the spindle. By meansof a cord grip of ordinary construction'the spindle cord is gripped whenit is slackened so as to insure that the spindle will stop.

The cord tension lever 15 extends over a short distance front of itspivot 14: and

carries on a T shaped adjusting screw .17,

tefision lever 151s raised to its highest point p At the inner end 18 ofthe horizontal limb 18 of the vertical rod 18 I .fix a cross pin 21which passes beneath the horizontal limb 12 of the bell crank lever 12and which lifts the bell crank'lever 12 when the vertical rod 18 isdisengaged and rises. On the end 18 of the horizontal limb 18 of thevertical rod 1 fix a hand lever 22 standing upward to enable thG WOIkBIto draw the vertical rod 18 clear of its catch at its inner end.

plate 19 and thus stop the spindle l and raise the top delivery roller10 clear of the low delivery roller 9.

hind the low delivery roller 9 I mount a trough 23 in which a liquid isplaced for the purpose of damping the strip of paper or other material 6Behind and above the trough 23 I mount a horizontal shaft 24 in suitablebearings which are carried on the to rrail 8. At the end of the saidshaft 24 a hand quadrant 25 by means of which the shaft is turned on itsaxis and fixed at any particular point after described.- On this shaft24 I mount loosely a} dip lever 26 with a limb projecting forward overthe edge of the trough. On this dip lever 26 I mount on a stud a looseroll 27 which dips into the liquid in On the shaft 24 carrying the diplever 26 I fix a boss having a cross pin 29 passing under and supportingthe dip lever 26 so that on the shaft 24 being operated by the quadrant25, before referred to, one way or other the dip lever 26 is loweredintoor raised partly or entirely out of In this way the depth to which thedip roll a' enters the liquid may be ad justed. 'The shaft 24; referredsimilar dip levers for a gpoup of spindles. By means of the'quadrant 25all the dip levers 27 mounted on the shaft areliited clear of the liquidwhen the frame is stopped so astoprevent ove -damping porarily. Toaccomplish this I 19.

suitable supports 34. The spindle l and delivery roller 10 being stoppedand the dip starting lever 31 is then pressed down at its frontend'causing the spindle l and delivery roller 10 to start and the diproller 27 to enter the liquid. It will thus be understood, then thewhole of the spindles of the frame are stopped, by means of the shaft 94the p levers 27 are raised out of the trough carrying the paper stripsor other material 6 clear of the liquid and also that when the spindle 1and delivery roller 10 are stopped, at the same time, the dip lever 26of the spindle is lifted clear of the liquid, thus preventing the paperstrip or other material from getting over-damped and weakened.
